Welding 5mm thick pipe to 12mm thick pipe
Thread Content
The outer diameters of the pipes are the same, and the circulating medium of the pipes is hot air. If groove welding is performed, can it be butt welded?
Of course, butt welding is possible. When welding, pay attention to the direction of use of the welding rod, so that the arc burns the thick side of the pipe wall as much as possible, and the thin pipe wall can be welded through.
Thick-walled steel pipes are beveled with blunt edges.
It can be butt welded and beveled for thick-walled pipes, but it must be welded through.
The thick pipe should be thinned to a length of not less than 4 times the thickness difference between the thick pipe and the thin pipe, and then welded using a full penetration groove with a blunt edge.
Yes, the inner wall of the thick-walled pipe is thinned to be flush with the thin-walled pipe, and butt welding can be achieved.
Of course you can, just bevel the pipe and weld it through. But I think it’s a bit unbelievable and wasteful to use 12mm wall thickness pipes to transport hot air.
It should be possible. The pipes we use have the same inner diameter but different wall thicknesses. But how can you use 5mm and 12mm pipes on the same pipeline? It is best to use pipes of the same diameter for safety! !
